A milky discharge from the nipple and breast hypertrophy are often seen in mature infants, but bloody nipple discharge is very rare in infancy and childhood. In adults, a bloody discharge may be associated with breast carcinoma, but in infants it is a benign, self-limited condition that should be managed conservatively. Surgical procedures should be avoided, because injury to the breast bud may cause permanent damage. We report a 3-month-old girl who presented with a bloody discharge from the left nipple. The discharge diminished gradually in the course of time and ceased completely at the age of 9 months.
